We divide 54369175 by 343
The aim is to understand the frequency of 343 in 54369175.

Moving on to step 1:
When dividing 5 by 343, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 343

Advancing to step 2:
343 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 343

Going ahead to step 3:
343 goes into 543 1 times with a remainder of 200.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 200 after subtracting 343 from 543.
Grab the next digit (6) from the dividend, add it to 200, then carry on: 2006 / 343

Step 4:
When dividing 2006 by 343, we get 5 with a remainder of 291.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1715 from 2006 to get 291.
Append the next digit (9) from the dividend to 291 and continue with: 2919 / 343

Moving on to step 5:
When dividing 2919 by 343, we get 8 with a remainder of 175.
Use 8 as the next digit of our solution. 
Result so far: 158.0
Subtract 2744 from 2919 to get 175.
Fetch the next digit (1) from the dividend, attach it to 175 and continue: 1751 / 343

Advancing to step 6:
When dividing 1751 by 343, we get 5 with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 1585.0
Subtract 1715 from 1751 to get 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 343

On to step 7:
If we divide 367 by 343, we get 1 and a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 15851.0
If we subtract 343 from 367, we get 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 343

On to step 8:
343 goes into 245 0 times with a remainder of 245.
The next digit of our result is 0. 
Result so far: 158510.0
If we subtract 0 from 245, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 9:
343 can be fit into 2450 7 times, resulting in a remainder of 49.
The next digit of our result is 7. 
Result so far: 158510.7
If we subtract 2401 from 2450, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
490 divided by 343 is 1 with a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 158510.71
If we subtract 343 from 490, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 11:
When dividing 1470 by 343, we get 4 with a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 158510.714
The remainder is 98 after subtracting 1372 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
If we divide 980 by 343, we get 2 and a remainder of 294.
Put 2 as the next digit of the answer. 
Result so far: 158510.7142
Subtract 686 from 980 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 13:
343 can be fit into 2940 8 times, resulting in a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 158510.71428
The remainder is 196 after subtracting 2744 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 14:
If we divide 1960 by 343, we get 5 and a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 158510.714285
Subtracting 1715 from 1960 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 15:
The number 343 fits into 2450 7 times, leaving a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 158510.7142857
If we subtract 2401 from 2450, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
When dividing 490 by 343, we get 1 with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 158510.71428571
The remainder is 147 after subtracting 343 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Our division results in 158510.71428571 with a remaining 1.47e-07.
